Image to crochet pattern
AI suggests stitch width and colours from your picture. Compare the chart, then make it yours.
Workbench
One picture, two settings, and a chart you can correct by hand. The free workbench runs on your device: turn a photo into a crochet pattern with no account and no automatic upload. The optional AI draft sends only what you explicitly submit when you click Generate above.
Image to crochet pattern converter: how it works
Four steps, one browser tab, no accounts. Use it to convert a picture into a crochet pattern from a JPEG, PNG or WebP you own.
- One square is one stitch.
- Heavier lines every ten stitches.
- Letters match the legend, so a grey print still reads.
Choose a picture
JPEG, PNG or WebP, up to 25 MB. It is decoded with the browser’s own image decoder and scaled to a 1024 px working copy.
Set the size
Stitches across is yours to pick; rows come from the picture’s proportions. Each square averages the pixels underneath it.
Set the colours
Median cut splits the colour box along its widest side, again and again, until it has your count. No randomness, so the same inputs give the same palette.
Correct and save
Repaint any square, swap a palette colour for yarn you own, then save a PNG sheet or a one-page PDF with the legend.
Reading the chart
- Turn the image into a crochet graph: one square is one stitch, heavier lines mark every ten stitches, and letters match the legend so a grey print still reads.
- Colour count is yours to cap between 2 and 12; extra similar shades get merged.
- Gauge is not converted, so check a swatch before you trust the finished size. Edit any square, then save a PNG sheet or a one-page PDF with the legend.
What this MVP does not do
- Gauge is not converted. One square is one stitch, and stitches are rarely square — check your own swatch before trusting the finished size.
- Palette colours are plain descriptions. There is no yarn brand mapping and no claim of compatibility with any commercial colour standard.
- The standard Undo button covers square edits. AI chart Apply has its own complete Undo until you make another edit or change the reading view. Changing a palette colour or rebuilding the chart is not part of the undo history.
- Closing the tab clears unsaved changes. Download an editable chart file to keep your chart and open it here later.
Common questions
Short answers about files, printing, colours and what stays in this tab.
Does my photo leave this page?
Local chart tools do not upload your picture. Only when you click Generate, optional AI receives a reduced JPEG copy (up to 512 px and 64 KiB), your goal and chart totals. The original file and filename stay in your browser. Sign in with Google to view actual AI availability, packs and credit balance; local tools need no account.
What pictures can I use?
JPEG, PNG or WebP files up to 25 MB. Use a picture you own or are licensed to use. Large photos are scaled down in the tab before charting.
Does this map yarn to a commercial colour standard?
No. Palette colours are plain descriptions. There is no yarn brand mapping and no claim of compatibility with any commercial colour standard.
Can I print the chart?
Yes. Save a PNG sheet or a one-page PDF that includes the grid and a lettered legend. Gauge is not converted; check your own swatch before trusting finished size.
How many stitches and colours can I use?
Stitches across runs from 16 to 120. Yarn colours run from 2 to 12. Rows follow the picture’s proportions and are capped at 220.
How do I read the chart?
One square is one stitch. Heavier lines mark every ten stitches. Letters match the legend, so a grey print still reads. Gauge is not converted; check your own swatch before trusting finished size.
